Overmolding Service

Industries including robotics, medical and automotive use overmolding for manufacturing aesthetically pleasing products or to reduce the assembly line stations. Overmolding offers a more convenient solution for injection molded products with two or more materials.

Prolean’s overmolding services offer all the different combinations for overmolded parts with a wide range of materials to choose from.

What is Overmolding?

Overmolding is an injection molding process where a composite product is manufactured with two or more materials.

Industries use overmolding a lot. Everyday plastic product handles with rubber grip are a common example of overmolded parts.

Such parts often have easy-to-spot lines separating the two materials.

Advantages of Overmolding

Overmolding has one primary advantage. One machine can generate multiple pieces of the part directly on each other. This reduces the number of machines and assembly line stations required which saves a large amount of time and money.

Overmolded parts have a broad range of applications due to their composite nature. Grips, seals, insulation, and vibration-absorbing layers are often over-moulded on products.

Finishing Options For Overmolding Product

As the machined or deburring

The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).

Bead Blasted

Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.

Polishing

Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.

Powder coating

Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.

PTFE (Teflon) Coating

The Teflon layer on the parts offers excellent corrosion resistance, water resistance, and non-stickiness with a non-reactive surface.

Brushing

Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
